Creating a bootable macOS Ventura installer can be desirable for many advanced Mac users, whether to perform clean installations, install macOS Ventura 13 onto multiple machines without having to re-download the installer, to serve as a recovery boot disk, or any other number of reasons.

Making a macOS Boot install drive is not particularly difficult, but it does require using the command line.

Before getting started, make sure you have the following prerequisites covered:

• Download the macOS Ventura installer application to the Mac /Applications folder if you haven’t done so already
• A macOS Ventura compatible Mac
• A 16GB or larger USB flash drive which will be erased to create the installer drive

How to Make a MacOS Ventura Installer Drive

Creating the boot installer takes a few steps:

1. Connect the USB flash drive that will become the boot installer to the Mac
2. Rename the USB drive something obvious, like “VenturaUSB” in the Finder
3. Open the Terminal application on the Mac by hitting Command Spacebar to open Spotlight, then typing “Terminal” and hitting return
4. Enter the following command string into the terminal, the following syntax assumes you named the USB installer drive as ‘VenturaUSB’: sudo /Applications/Install\ macOS\ Ventura.app/Contents/Resources/createinstallmedia --volume /Volumes/VenturaUSB --nointeraction
5. Hit return and enter the administrator password
6. The macOS Ventura boot installer drive will be created and the Terminal will update on progress and completion

When you’re done, you can eject the USB installer and use it on any compatible Mac with Ventura by booting it like any other bootable drive.

The boot installer can be used to upgrade other Macs to macOS Ventura 13, or to perform clean installations.
